Color shift on Google Drive

[RMW]

Hello All.
Not sure where this belongs so I'll start her.
Working towards a book. Uploading 90 fotos onto Google  Drive for submitting to a publisher. The first try went well. The colors  were good. When I uploaded a revised folder of the fotos the colors shifted a lot. When I reloaded the folder the results were a little better, but still not satisfactory.
The fotos are between 5 and 15 MBs, in Tiff, flattened, and in ProPhoto.
Any help will be greatly appreciated.

Ps- sent a query to GD 2 days ago with no response so far.

Was the embedded profile (ProPhoto) stripped?

Andrew,
Thank you for responding.
Not sure if it was stripped. Don't actually know what "stripped" means.
I did flatten the file by going into Layers.

Get a document off Google Drive (FWIW, I don't use it, no idea how it deals with documents).
Open back up in Photoshop: there should be an embedded ICC profile stating it is in ProPhoto RGB. AND look OK.

Got a file off G.D. Put it into PS. Under Edit chose Color Settings. Says it is in ProPhoto RGB.

PS- It did look OK.

And it looks OK right?
So where's the issue: "fotos the colors shifted a lot" where?
Photoshop is color managed; anything that doesn't match isn't.

Colors shifted on some of the fotos, but not on others. What's curious to me is that the first upload looked good. But I decided a few of the files were a little off. So I copied the original files to  a new folder, tweaked a few, uploaded the folder and saw most of the fotos were way off. I can't say I say a pattern, but the blues in the sky, in many of the files, were a bit purplish.

Assuming you used a web browser to upload your photos to Google Drive, the destination files are bit-for-bit identical to the source files.  Google Drive doesn't alter anything: it's simply another storage medium.

If you uploaded the files with some other client application software that uses the Google API  (i.e., a program other than a web browser), I suppose it's remotely possible the client could have done something squirrily during the upload process — but that strikes me as extremely unlikely.

More likely, some change in your local environment, or in your publisher's.
