This is not true, only L&L pays less in disputes team.

Yeah, much lower and negligible bonuses compared to corporate, I've heard.

Also, would it be possible to make a shift from corp to disputes at say the A2-SA1 level? I find myself at the other end of the question - have corp internships and call-back but an eventual goal of entering litigation

The pay in disputes is lower than in corporate?

Will be joining a disputes team at a tier 1 as an A0 next year as many of my internships incidentally were in that area. However, I've heard the pay disparity is very high, so I was wondering if a switch is possible at this stage. Corp experience would also allow a shift to in house at some point which (in my limited knowledge) disputes doesn't.
