This is an actual stereograph, not an artificial 3D conversion made from a single 2D image. The 23-minute 52.9-second interval between two JunoCam images taken during the time lapse sequence of Perijove 20 (29 May 2019 at 09:28:28.990 and 09:52:21.844 UTC) established a stereo base (camera separation) of thousands of kilometers, from which this stereographic image pair was crafted using Photoshop. Thanks to the velocity of Juno, the distance traveled during the interval between these two captures effectively gives our eyes that same separation. Viewing Jupiter at a known average altitude of 139,608.85 km (86,748.8 miles),
it's nevertheless possible to perceive features of the atmosphere three dimensionally. Juno's actual speed and, thus, the stereo base for this image pair from Perijove 20, is unknown (at least to the creator of this stereograph). Note that during the 23-minute 52.9-second interval, Juno ascended 38,978.9 km 24,220.3 miles), from 120119.4 km to 159,098.3 km (an 32.45% gain in altitude), requiring relatively extreme z-axis correction (compared to JunoCam-sourced stereographs made with shorter durations between exposures) in addition to x- and y-axis skewing, to produce the stereograph.
