i doubtthat laserdisc stores its audio at the same sample resolution.
dvd probably supports more modern surround sound too, if laser disc supports any.

Almost all DVDs that have 2.0 surround tracks are encoded to compressed AC3, most laserdiscs that have digital audio are uncompressed PCM.
en.wikipedia.org/wiki/Laserdisc
"Audio could be stored in either analog or digital format and in a variety of surround sound formats; NTSC discs could carry two analog audio tracks, plus two uncompressed PCM digital audio tracks, which were CD quality and PAL discs could carry one pair, either analog or digital. Dolby Digital (also called AC-3) and DTS, which are now common on DVD titles, first became available on Laserdisc, and Star Wars: Episode I (1999) which was released on Laserdisc in Japan, is among the first home video releases ever to include 6.1 channel Dolby Digital EX Surround. Unlike DVDs, which carry Dolby Digital audio in digital form, Laserdiscs store Dolby Digital in a frequency modulated form within a track normally used for analog audio. Extracting Dolby Digital from a Laserdisc required a player equipped with a special "AC-3 RF" output and an external demodulator in addition to an AC-3 decoder. The demodulator was necessary to convert the 2.88 MHz modulated AC-3 information on the disc and convert it into a 384 kbit/s signal that the decoder could understand. DTS audio took the place of the PCM audio tracks, and required only a direct connection via Optical Audio cable and a decoder to be heard."
