Samsung drives with MTK chipsets are capable of scanning but the functionality is blocked (god knows why) in CD-DVD Speed by default for TSSTcorp drives. You may know this already, but in case you don't, you can remove this block by erasing TSST and Samsung through registry settings for Nero CDspeed as outlined in this post.
There is no such thing as reliable scans. The drive either provides the information on how it read the disc (PIE, PIF, POE, Jitter, TA Jitter) in the correct format expected or it does not. In the case of MediaTek-based Samsungs you can expect correct representation of PIE@8ECC and PIF@1ECC values, and you can expect no Jitter and POE reporting whatsoever. As for the usability of the scans and correlation to scans of more popular scanners these days (Liteon and Benq), which is what you are really asking about I can say that from my experience with older Samsung drives (when they were still good, ie. before 2 letters at end of model #) there is fairly good correlation, with the occasional hiccups but generally I would feel OK relying on the scans. The hiccups are that Samsung likes to reads its own burns better (report lower PIF than the other drives mentioned) and sometimes has a harder time reading CLV burns of other drives. Variation is expected with any drive though, its not an exact science so I don't see anything bad here.
I will comment on build quality of Samsung by just saying that it went down significantly when the models with 2 letters at the end of the model number (such as your SH-224BB) were released. Before that I think Samsung's DVD writers build and burn quality was indeed superior to some Liteon DVD burners and also LG, as were the firmwares. After ~2011 or whenever the SH-222AB came out they have been on par or worse than the Liteon's and LG has taken over quality burning. It has to be noted though that I don't consider new LG Renesas-based burners superior to old Samsung drives (SH-223 and earlier), rather the opposite. They are simply the best you can buy new right now at computer hardware dealers (not counting new old stock on ebay, or Pioneer elitists opinions).
This conversation about Samsungs reminded me I had got (yet another) new SH-203B drive a while ago, to replace my iHAS624B (which will be used as backup/special occasions due to higher value as scanning/ripping drive). I did that today and posted a scan of a burn of the same MCC 004 batch made in September 2016 by CMC as I burned on the LG GH82N (you also seem to have a Sep 2016 batch). You can find that here. I also included a scan of the disc by that same drive, notice the similarity in results to the other scanner drives. This burn is clearly better than LG's, but it is their best burner (and from 2008) so that's no surprise.
