I doubt “the closest” statement is correct. Parker Solar Probe got as close as 0.125 au (and that just so far), whereby the closest Solar Orbiter gets is 0.284 au.
This statement is being reported in many places. Maybe Parker Solar Probe did not have any instruments that capture wavelengths in the visual spectrum and compile them into images.
Parker Solar Probe indeed got closer, but did not take photos of the sun from that point. Another important detail that is a bit confusing is that this is also not the highest resolution image taken of the sun. Ground based telescopes have taken higher resolution images, however, they cannot image in EUV because EUV is absorbed by the atmosphere. (So, this is likely the highest resolution imaged in EUV, which is necessarily a space-based observation.)
