Pyrex is inherently stronger than ordinary glass, which may be why it was used by EMI for CRTs before WW2. I have no idea if they used the extra strength to make the CRTs of thinner glass.
If a CRT implodes, I don't think there's going to be much difference between Pyrex and soft glass. There will be lots of nasty small, sharp fragments flying. Toughened glass, used for some windows, historically for car windscreens, shatters into relatively blunt edged peices.
