LG OLED vs Samsung RGB: I tested the two brands' latest flagship TVs side-by-side using reference 4K Blu-ray scenes — here's which one came out on top

RGB TVs are the latest talk of the TV world, with multiple brands embracing the new technology.

Known by different names depending on the brand, such as Micro RGB (Samsung and LG), True RGB (Sony), and RGB mini-LED (Hisense and TCL), RGB TVs use a layer of red, green and blue mini-LEDs in their backlight, where standard mini-LED just uses white LEDs.

The aim is to produce bolder, richer colors and better backlight control compared to traditional mini-LED.

I’ve tested a few RGB TVs now, and the tech shows promising signs.

One of those TVs, currently sitting in our testing lab, is the Samsung R95H, the brand’s flagship Micro RGB TV.

I’ve compared the R95H to a rival True RGB TV from Sony, the Bravia 7 II , and both showed what RGB is capable of.

But, given that RGB is aiming to take OLED’s spot at the top of the best TVs pile, I thought I’d compare the R95H to a rival OLED, using reference scenes from 4K Blu-rays I use in my AV testing.

The OLED I’ve chosen is the LG G6, one of the best OLED TVs I’ve tested so far in 2026.

So, let’s find out how a flagship OLED compares to a flagship RGB TV.

A quick note on the photos below: the R95H has a red tint due to the camera interacting with the glare-free matte screen.

This red tint is not visible when viewing with the naked eye.

Brightness Both TVs deliver big brightness, but surprisingly it's the LG G6 OLED (left) that has punchier highlights and brightness, shown in this shot of Speed Racer (Image credit: Warner Bros / Future ) Traditionally, mini-LED would take the brightness crown easily, as mini-LED in recent years has easily exceeded 3,000 nits, even in budget models, while OLED has struggled to break the 2,000-nit mark.

However, that’s changed in the last couple of years, with OLED now delivering real brightness improvements.

Measuring both TV’s brightness, the LG G6 initially hit 2,471 nits peak HDR brightness in my first tests in March 2026.
