Upscayl, the local AI image enhancer is getting better and better

Blimey am I happy! Two in a row! Here's a most fantastic, highly enthusiastic, follow-up review of Upscayl, a cross-platform offline local AI image enhancer software, tested on a Linux system with hybrid Nvidia graphics, including new features and models since the last report, improved rendering times and results, differences in output quality and suitability among various models, optimal settings for urban, nature, people and mixed conditions, blur and lighting effects, batch mode and before-after zoom, some other observations, and more. Enjoy most greatly!
