Advice on stock firmware compatibility

I have a Sprint Moto E on 5.0.2 and would like to upgrade it to 5.1, but the only stock firmware I found for the hardware model I have (XT1526) comes from boost (Sprint MNVO). My question is: is that ROM compatible with my phone? Alternatively, does anyone have or can share the Sprint 5.1 version? Maybe another stock ROM would work? Please shre some advice, much appreciated!

For he record, the available stock firmware that I am refering to are here and here.
