Our Verdict
Sony A9G OLED
LG SM9970 8k
The Sony A9G OLED is significantly better than the LG SM9970 in mixed usage. Since the Sony is an OLED TV, its contrast ratio and black uniformity are much better than the LG. Also, the Sony has better gray uniformity and viewing angles, but the LG can get brighter in both SDR and HDR content. However, the Sony has a risk of permanent burn-in, while the LG doesn't, since it has an IPS panel.
