TCR looks curved to me.

No, they're straight:

I thought that the platforms would be straight as, IIRC, current
legislation stipulates only straight platforms.

Plus, it's a given that HSE would probably have conniptions if they saw
a curved platform. So, even if it is legally possible to build a curved
platform, it would not surprise me if the engineers and designers
decided simply to build it straight in order to avoid any
"complications."

They obviously don't have to be ruler straight, but I assume there are
rules for what (large) radius is allowed. You certainly wouldn't be
allowed to build anything like the Central Line Bank platforms today.

I don't think the rules have changed since Canada Water East London Line
platforms were built, and IIRC that is on a fair slope, so the rules can
be broken if TPTB feel like it.
