I originally planned to have a style up the center of the back separating 2 mirrors for additional shelve brackets. The brackets will be on the 4 corners and no style in the front where the 2 doors meet.
If I use 3/8 thick shelves will the 4 corners offer enough shelve support with no style in the back considering no stacking of china?
Thanks in advance

Here is a glass calculator
calculator.
If you go with tempered glass suggest you build the cabinet to standard sizes as it will be a lot cheaper. Is your V notch cut in the glass shelves ? If it is it may affect the load capacity. Roly

What we use for a liquor cabinet is an old china cabinet with similarly sized shelves (almost exactly). They are not thicker than 1/4, and only supported by four shelf pins. Even loaded with bottles, there is minimal deflection in the middle. I would think 3/8" would be more than enough with only edge support.

Sagulator suggests that 45 - 50 pounds is the most that should be loaded on a shelf of that size.

How big are you planning to make the V-groove? How are you planning to make the groove?
Unless you have a good way to deal with the microcracks introduced by that machining, I would suggest doing the strength calculation based on the thinnest part of the shelf under that groove.
Even then, it might be a good idea to use 3 brackets/pins on each end. Otherwise, you are putting all of the weight on the pre-cut to shear the shelf.
I don't recall where you are located. If you are in an earthquake zone, then you might want to add some extra safety margin to the strength calculation.
