Ideal desktop contrast ratio

[silikone]

For a long time, it seems like the contrast ratio of typical flat panels has with a few exceptions stagnated at 1000:1. With the advent of HDR, we're finally seeing contrasts skyrocket. However, is it the right thing to retrofit SDR desktop environments with these advancements? There are two problems that I see with doing this.
First, with only 8 bits per RGB channel, there just isn't enough precision to avoid banding as it is, even with a properly calibrated display. Low contrasts somewhat hide this, but in synthetic tests such as long quantized gradients, the transitions are evident, and this only becomes worse as the contrast of the screen increases.
Second, the sRGB standard that almost everything in the PC world adheres to comes with its own transfer function, and if this is to be followed faithfully, a fully 8-bit encoded dataset with clamping would cover a range with a contrast ratio no more than 3500:1.
Assuming an image has been converted or rendered directly to sRGB (discouraged by professionals) from pure linear data, having it displayed on a high-contrast HDR screen would make it surpass the contrast of reality!
With this in mind, is there any right balance suitable for SDR gaming and desktop use that existing products have settled for?

Contrast ratio has certainly stagnated for years, and the HDR boom is pretty welcome.

The world has retina-ized resolutions, so it's time to retina-ize dynamic range. HDR time, baby!
(And yes, other stones unturned too: Blur Busters raison d'être, future retina refresh rates ala 1000Hz+)

Current king of desktop gaming contrast ratio is the new 384-zone local dimming monitors, utilizing GSYNC HDR:

Acer Predator X27 - 27" IPS 3840x2160 144Hz
ASUS ROG Swift PG27UQ - 27" IPS 3840x2160 144Hz
HP OMEN X Emperium 65 - 65" IPS 3840x2160 144Hz

These displays shatter the 1000:1 contrast ratio barrier, but are currently extremely expensive.
The first two are desktop size, and the last one is a BFGD.

Desktop OLED gaming monitors are already currently in development, though are subject to the usual 1-to-2-year monitor engineering lifecycle, so expect some high-Hz desktop OLED by end of this year (more realistically 2020). Fingers crossed.
