Ken browsers mostly ignore the color space. For anything for the web, sRGB
is the right choice.
Even if your monitor is profiled correctly and supports a wider gamut than
sRGB (most don't) your browser won't use that profile.
On your screen when looking at your pics in Photoshop or another color
management aware program you will see the rendering in as large a color
space as your monitor and video card support. That is providing you have
color management set up correctly. When you install new versions or new
programs, you should check that those color management settings are
synchronised.

Bob's shot of Buddy the pup looks perfectly fine here (clean whites
rendition of the fur) on the laptop I use for my email. This screen is
adjusted fro 6500K but otherwise not calibrated.

Notice how many times I wrote "color " in deference to your location ;-)

The gallery software can be set for whatever sizing options you want
although most people don't seem to do that. Mine is set to show the size I
upload. I have never observed any colour ;-) shifts on sRGB files I
uploaded here comparing browser and Ps/LR view of same file.
