As a follow up to that I checked the speedometer today because I thought, there is no way I’m going 90 every time I get on the freeway, the speedometer is probably as accurate as the fuel gauge! Test completed, I’ve been going 90 on the freeway. 🤣
Fuel gauge

if I were you, I would have already gone back to my reseller ...
The fuel gauge inaccuracy is a known thing in most Yamaha models (MT07, 09, 10 etc)
Usually it shows full for the longest time after refill, then VERY rapidly loses bars and into reserve light.
Think people just learn to live with it and estimate fuel by miles traveled instead of the fuel gauge.
From R7 manual:
Fuel tank capacity:
13 L (3.4 US gal, 2.9 Imp.gal)
Fuel tank reserve:
2.5 L (0.66 US gal, 0.55 Imp.gal)
From experience with riding my MT07 (still waiting for R7)
Average fuel consumption 57mpg (4.96/100km)
So once the reserve light comes up you have about 30miles/50km (a bit more if you go full fuel saving mode).
Do a few full tank to reserve light rides so you can figure out how many miles you can do with your riding style
Reset one of the trip meters when you refill and keep track of that every once in a while when you ride.
Here's also a fun fact from the MT09 but a similar thing should apply to other models.

Semi unscientific test:
Reserve light on at 77 miles
Rode another 24,7 miles in reserve mode
Siphoned approximately 1 gallon of gas out of the tank. (Just under 3gal is where it started on the can, just under 4 is where siphoning stopped. Hard to tell on this old can, that's why I drew lines)
Added back approximately 3.2 gal (You can see the can level here)
Filled to the brim, gauge shows one bar below full
My guess is reserve mode comes on with around 2 gal in the tank. Which pretty much goes in line with just hitting reserve then adding less than 1.5 gal at the gas station. I'll still fill up soon after hitting reserve mode, but I am thinking we can go a lot further that we think. YMMV
