Your head is buried deep alright, but that isn't sand.

Having changed from AT&T dialup to AT&T Fiber in late August
and having watched (at a distance of about 3 ft.) a few movies
via the (free w/Fiber) HBOmax, I haven't seen any video artifacts
(W10 Edge browser, Compaq S1922s monitor).

Google reveals that HBOmax currently doesn't allow user
selectable resolutions.

My question is could an older technology by applied to streaming
playback to reduce possible video data reduction artifacts?

Example of Block NR and Mosquito NR for VideoCDs:

I haven't read about any streaming playback NR systems designed
to minimize the visual effect of too low a video data rate, is there
any such NR system (now or under development)?

video compression artifacts are usually more pronounced at very dark or very bright scenes. Normal methods like noise reduction are irrelevant. AI or Neural Network processing is what is used. Newer 8k TVs are using AI up scaling techniques. A example of neural procession is cleaning up 100 year B&W film and colorizing it.

Reduction of Video Compression Artifacts Based on Deep Temporal Networks - IEEExplore

Quote:
Abstract:
It has been shown that deep convolutional neural networks (CNNs) reduce JPEG compression artifacts better than the previous approaches. However, the latest video compression standards have more complex artifacts than the JPEG, including the flickering which is not well reduced by the CNN-based methods developed for still images. Moreover, recent video compression algorithms include in-loop filters which reduce the blocking artifacts, and thus post-processing barely improves the performance. In this paper, we propose a temporal-CNN architecture to reduce the artifacts in video compression standards as well as in JPEG. Specifically, we exploit a simple CNN structure and introduce a new training strategy that captures the temporal correlation of the consecutive frames in videos. The similar patches are aggregated from the neighboring frames by a simple motion search method, and they are fed to the CNN, which further reduces the artifacts. Experiments show that our approach shows improvements over the conventional CNN-based methods with similar complexities for image and video compression standards, such as MPEG-2, AVC, and HEVC, with average PSNR gain of 1.27, 0.47, and 0.23 dB, respectively.
