No, I can confirm that you do not need to worry.
As the software displays the status is PERFECT, there are no problems with the SSD.
Yes, the health is not 100%, "only" 92% - but it is still high.
As you may know, the memory cells in solid state devices experience wear during each write operations and each cells tolerate only a limited
number of overwrite passes.
The "wear-leveling" feature of the SSD tries to hide/minimise this effect but generally the SSD device reports the overall health of the memory cells
by various attributes.
If there are no further problems found, Hard Disk Sentinel reads these attributes which determine the complete health of the solid state device.
This is what you can see in the text description area: there are no problems found, but the 177 Wear Leveling Count attribute determines the overall health of the device. If you want, you may check how that attribute changes with time on the S.M.A.R.T. page.
This is completely independent from software, OS, restarts and so: as the amount of written data increases, the health slowly but surely decreases.
This is normal - and you do not need to worry about it now, as only 8% of the total lifetime used.
Please note that usually the health decrease is not linear, it will be faster - but there is still lots of time until the drive needs replacement.
Personally I'd consider replacement around 50% only.
To extend the drive life, please try to minimize writes to the SSD.
