I'm not sure that tablets are still being made with IPS screens.

Yes they are. And large screens. IPS LCD is longer life than OLED/AMOLED which are not "real" LEDs, but printed electroluminescent diode dots with phosphors printed on top. There is maybe less light loss with OLED/AMOLED but a maximum brightness due to dot dissipation and phosphor. The Colour LCD (IPS or not) have three main losses: The liquid crystal, polarising filters and the RGB or RGYB filter. LCDs use real LEDs as backlights, either blue-violet (or near UV) with phosphor or R, G & B true LEDs (usually only more expensive TV screens). The last CCFL backlit colour phones about 2002 and last CCFL TV sets maybe about 2012.
So in theory an LCD could be brighter than an OLED/AMOLED display, but in practice usually isn't. Shiny glass is common even on laptops, monitors and TVs because proper matte surface glass is much more expensive. It's micro etched, though if you rub for hours with non-gel toothpaste it helps. Don't use ones like "Pearl Drops" as it might be too abrasive. Check on a CD case to see there are no large scratchy particles.
The eink screens are horribly expensive compared to OLED/AMOLED or LCD, so tend to be micro-etched to reduce reflections as it's a lower percentage of the cost and it's needed for the sunlight advantages.
