Plans

The company I work for has a 'creative cloud all apps' plan and also a 'photography plan'

Keep in mind that unless the company has a Teams or Enterprise account, use of the subscription is limited to the person whose account it is.

No.

If you decide to cancel the photography plan, though, make sure that you've downloaded all your files from the cloud to your own system(s). Also check the time remaining on the subscription. If there's more than 6 months left, you're better off waiting until the final month to cancel since otherwise you're paying a penalty. 

the all-apps plan includes everything that's in the photography plan and much, much more.  so no, you do not need (and have nothing to gain with) the photography plan if you're going to get the all-apps plan.
