I'm looking at it on a Dell U2715H, which is not a professional display, just a consumer one with above-average color quality and good calibration out-of-the-box, and I could spot the temperature shift immediately as well. Also, as you say, the details are bad.

I'm wary of services that auto-compress images, because a) I want my bits to stay the way they were originally captured, and b) every now and then I have to print a photo I make, and then suddenly all those details matter for the print quality.

It's a non-issue with a Google phone (a Pixel) in any case, as you have unlimited storage of photos in their original quality.
