The short answer is no. But there can still be duplicate photos in iCloud.
iCloud Photos can detect exact duplicate photos (photos that are exactly identical regardless of name) during upload. If you upload a photo that is already in your iCloud, a “Duplicate photo” message will appear, and the photo won’t be uploaded. If you upload two exactly identical photos, one will be uploaded, and the other will be ignored.
So why are there still duplicate pictures in your iCloud?
One reason is that iCloud can’t detect near-duplicate photos (photos that look the same but are different in formats, resolutions, file sizes or metadata, and similar photos) at all during upload.
Another reason is that the duplicates on your Mac, iPhone or iPad can be synced to iCloud if you use iCloud Photos on your device.
There can be other reasons. Also, iCloud doesn’t provide the feature to recognize duplicates that already exist in your account.
For Mac users who want to keep the iCloud photo library organized and free up space efficiently, the best way is to use Cisdem Duplicate Finder, which can find both exact duplicates of pictures and near-duplicate pictures in your iCloud.
1. In the Photos app on your Mac, go to Settings.
2. Under the iCloud tab, select the iCloud Photos checkbox. (In earlier macOS versions, iCloud Photos was called iCloud Photo Library.)
3. Photos will start syncing between iCloud Photos and the Photos app. Wait for the sync to finish, and you will have the same photos in both places.
4. Download Cisdem Duplicate Finder. Install the software and open it.
5. Drag your Photos library into this iCloud photo duplicate finder and remover. Click Scan.
Note: When you use this tool to search for iCloud duplicate photos for the first time, it will ask for permission to access your photos library. You can grant it permission by going to System Settings > Privacy > Photos. Then restart the app.
6. Once the scan is complete, the Images tab in the results window will display all the duplicate photos found in iCloud. You can preview and view them.
7. The software has automatically selected all exact duplicates for you to remove. Or, you can choose a selection rule or select by hand.
8. Click Delete to delete all selected iCloud Photos duplicates.
And when asked if you allow the deletion, click Delete to allow. Now the deleted duplicates will go to the Recently Deleted album in the Photos app.
At the same time, iCloud will automatically detect the deletion and sync the changes. If you go to iCloud Photos (icloud.com/photos), you will find that duplicate photos are removed from iCloud. And, they are now in iCloud Photos’ Recently Deleted.
If you have also enabled iCloud Photos on your iPhone, you will find that duplicate photos are also deleted on iPhone.
Note: By default, your Photos library is located in the Pictures folder. You can check the location by going to the Photos app’s Settings > General.
Tip 1. Find near-duplicate pictures in iCloud
To set this piece of software to find both exact duplicate photos and near-duplicate ones, you need to make sure that you have selected the Enable similar images function checkbox in the software’s Settings 
before you click Scan.
The identification of near-duplicate pictures is affect by the similarity level, which is adjustable. If you only want to find highly similar photos, you can set the level high. Setting the level lower will find more similar photos. You may need to adjust the similarity level several times to get the most satisfying results.
To view the near-duplicate photos that have been found, you need to go to the Similar Image tab in the results window. In each set of near duplicates, manually select the redundant photo(s) for deletion. You can also use the selection rules to help you select in bulk.
Tip 2. Delete duplicate photos in iCloud Drive
iCloud has a feature called iCloud Drive, which allows you to store images, videos, documents and any other types of files. If you are a Mac user and want to eliminate iCloud Drive duplicates, this tip is for you.
1. On your Mac, go to System Preferences.
2. Click iCloud. Sign in with your Apple ID and password.
3. Enable iCloud Drive.
4. Go to Finder and choose iCloud Drive in the sidebar. Wait for the sync to finish completely.
5. Open Cisdem Duplicate Finder. Click the plus icon and select the entire iCloud Drive folder or a specific folder within it. Click Open.
6. Scan for duplicates.
7. Remove duplicates.
Starting with macOS 13 and iOS 16, the built-in Photos app can now automatically detect duplicate photos and videos. It’ll scan your Photos library and put those found duplicates in the Duplicates album. You can find this Album in the Photos sidebar. To delete iCloud duplicate photos on Mac using the Duplicates Album, complete the following steps:
1. Make sure you’ve synced your iCloud photos with Mac Photos app. (The operation is the same as step 1-3 in method 1 above).
2. Go to the Photos app on your Mac. Click on Duplicates on the left.
If you don’t see the Duplicates album, here’re some easy fixes.
3. You can click on Merge x Items option at the top of each group of duplicates to merge the iCloud duplicate photos group by group yourself.
4. Or go to the Edit Menu. Click on Select All. Then click the Merge x Items option on the top right corner.
Click on Merge. Then you may have to choose between 2 options: Merge x Exact Copies Only or Merge x Items. The former option will only remove those exact copies. The second option will help you remove those exact copies, as well as merge photos that appear to be same but may have slight differences.

The disadvantage is that this method can only delete iCloud duplicate photos from iPhone Photos app. And it doesn’t offer selection rules to help you select duplicates to remove in bulk. Apple will keep the version that it thinks the best and delete others. Below’s a better method for iPhone users.

3. Zoom in photo thumbnails, compare them visually and locate the duplicates.
4. To remove a duplicate photo, select it by clicking its thumbnail and click the Delete icon.

Awesome. This post helped me a lot. I had about 8K photos in iCloud and there’re lots of duplicates. Now I’ve cleaned up them easily.
