The CRT in the Tek scopes, without the LCCS stack was quite bright!
Also IIRC, the Tek design actually used magenta, yellow and cyan filters, so perhaps JVC improved in the design?

A portion of text taken from JVC brochure:

"Unlike a conventional CRT screen, where the picture is written on the back of a light-absorbing layer, the TM-L500PN features a bright backlit screen seen through crystal-clear filters. Even if ambient light shines on the screen, the picture loses none on its contrast or clarity."

Maybe taking a bit of liberty here in their description.
