How to match colour space LR Cloud Version to PS

[#1]

How can I change the colour space in LR cloud version to match that in PS?
They look great when in PS, but as soon as images are uploaded to a website, they are flat and desaturated. I'm disappointed and so are my clients.
I cannot seem to find any editing preference settings in LR Cloud version to do so.
All help appreciated, thanks!
