 \nA faithful reproduction of gloss is inherently difficult because of the 
 limited dynamic range, peak luminance, and 3D capabilities of display devi
 ces. This work investigates how the display capabilities affect gloss appe
 arance with respect to a real-world reference object. To this end, we empl
 oy an accurate imaging pipeline to achieve perceptual gloss match between 
 a virtual and real object presented side-by-side on an augmented-reality h
 igh-dynamic-range (HDR) stereoscopic display, which has not been previousl
 y attained to this extent. Based on this precise gloss reproduction, we co
 nduct a series of gloss matching experiments to study how gloss perception
  degrades based on individual factors: object albedo, display luminance, d
 ynamic range, stereopsis, and tone-mapping operator. We support the study 
 with a detailed analysis of individual factors, following by an in-depth d
 iscussion on the observed perceptual effects. Our experiments demonstrate 
 that stereoscopic presentation has a limited effect on gloss matching task
  on our HDR display. However, both reduced peak luminance and dynamic rang
 e of the display reduce the perceived gloss. This means that the visual sy
 stem cannot compensate for the changes in gloss appearance across luminanc
 e (lack of gloss constancy), and the tone mapping operator should be caref
 ully selected when reproducing gloss on low dynamic range (LDR) display.\n
