It contains only one .ico file as far as I can see and the rest are PNG files. The .ico file is a favicon of only 32x32 pixels. I am not seeing the mix of 48x48, 32x32, and 16x16 favicon.ico images. Am I perhaps completely misunderstanding something here?
Perhaps that is what's unexpected here. Are you possibly looking at just the Windows "Details" properties of the file, which I see do portray the file as containing a 32x32 32bit-depth image.
ICO format is a container, which contains one or multiple images. That way a single .ICO file can contain best-representation images at multiple resolutions and color depths, which often require significantly altered or hand-tuned images for low resolutions or color depths as compared to the higher resolution versions contained in the same .ICO file.
The favicon.ico you're looking at in the favicon_package_v0.16.zip generated here actually contains three different resolutions of the icon image. Which is why in an ICO-aware application like IcoFx I showed a screen shot of, you're seeing "48x48 1", "32x32 1" and "16x16 1" all displayed down the left-hand side. (Citing the resolution and color depth of each image.) There could just as easily have been a single contained image, or instead a dozen or more contained images; but this favicon.ico has specifically these three (3) images.
So I'm guessing the favicon.ico you've generated for your site, at least through https://realfavicongenerator.net/
, actually does contain the same three different resolutions within the favicon.ico. And when you look at the contents of the favicon.ico file with a program that understands .ICO files, all three will be shown. Presuming you confirm that's actually true, it would mean there is no issue there and we're back to scratching our heads why Google has not yet accepted or updated the favicon.ico.

Out of interest, have you tried using the favicon from here as a test?
Well there's an important question I hadn't thought to check. Because neither phpBB's favicon nor my own site's favicon are being shown in Google Search results either. (D'oh!)
So even if the favicon.ico file format is
the issue, neither my suggestions nor Mick's suggestion would seem to hold the actual answer.
So now that's making me wonder whether we're actually looking at something more phpBB-specific. ChinaGal, can you look in the phpBB ACP General tab's "Spiders/Robots" section, edit the Google bot, and verify that the style selected for the Google bot to see actually is a style you've updated with your favicon.ico. e.g. That the Google bot isn't being shown an unmodified prosilver or similar, and so they don't see your favicon.ico at all.
That doesn't seem to be the case on my own board; Google bot is being shown the EA117-customized style just like guests are. And my favicon.ico doesn't show up in the Google Search results either. So there is probably more to the issue; but, if your phpBB wasn't showing bots the modified style, that too would be a problem.
