Lightroom / Photoshop image and exported image are different colours / colors
OK, so this is a weird one...
Up until about 2 weeks ago (start of Feb '19) everything was working fine. Then without any changes to preferences or any settings, this happened...
The image shown in Lightroom and the same image exported have huge differences in colour. The exact same thing happens in Photoshop.
The image on the right is in Lightroom and the one on the left is the exported jpg file.
(Though because I saved this screen shot using Photoshop the colours are off again.)
Weirdly enough, if I upload the overly saturated LR exported image onto any website like this one or Gmail, the over saturated image looks correct in colour and the correctly coloured image looks desaturated. This is until downloaded (by anyone on any device), then it looks off and over saturated again. I'm so confused!
I have no colour calibrating software working (I actually deleted it to see if it helped - it didn't), I have completely uninstalled and reinstalled LR and PS, and I have tried every export option possible with every colour space and file type.
Here is the image exported from Lightroom

Again, as I write this and look at the image it looks as it should, as I edited it in LR.
Here is a Dropbox link to this image jpg file so you can see it for yourself.
So from all of this, it might not be LR and PS after all but for some strange reason all applications (Google Chrome, LR, PS etc).
When viewed on my phone, on my computer with windows image viewer or uploaded to Instagram, that's when the image is over saturated.
I believe the true colour of the exported image is the saturated version and the programs are for some reason desaturating. But that's just my guess.
If you have any ideas, theories or an explanation I would be so grateful. I'm unable to edit images which means I can't make any money.
Please help!
