I have a problem with color profiles I guess...
So my Lightroom and Photoshop are both set to ProPhoto RGB.
I start with editing in LR first and then export to PS - so far so good - all colors look exactly the same on both applications.
Then when I'm done with editing in PS I convert to sRGB profile (Edit > Convert to Profile). After that action colors still remain the same inside PS.
However when I export the image (Save for Web or Export As) and check COnvert to sRGB and Embed Color Profile and then when open it with FastStone or Windows Photo app or any web browser colors look dull and desaturated compared to what they looked inside PS and LR.
What am I missing? For years I been editing images the same way as I described above and everything was working perfect until now. Did I change anything by accident and what could it be?
