Well I decided to be brave and give it a shot and change firmware.
WOW what a difference! The contrast is sooo nice and dark. I don't need a booklight no more!
There's no PC_Restore in file listing to bug me and for someone with eye vision issues this is a dream come true!

Fonts are crisp, clear and just gorgeous!

Menu is larger and easy to read as well.
The font rendering in MOBI is just 50% better with Lbook.
I could read in times font if I wanted before it looks like washed out newspaper print.
The only thing I notice so far is keys are less responsive.
The blank battery gauge in MOBI happens with this firmware as well as my old one but turning the device off then on fixes just like in Astak.
From a woman's perspective it's just prettier, brighter and nicer to use.
Edit: I just realized instead of file names it shows the Title name of the book!
