Mobile devices are an important part of daily communication, entertainment, and work, where videos, visual images, and written materials are presented on display screens. Common display technologies adjust or control the brightness of the display screen uniformly for all applications or uses. For example, traditional display devices (e.g., mobile devices, smartphones, etc.) are configured to adjust the brightness levels of their displays based on ambient lighting conditions or user preferences. Screens can be designed for display under various conditions that are potentially set automatically or controlled by the user: users may choose to reduce brightness to save energy or for a more comfortable viewing experience, or increase brightness for additional visibility. Conventional mobile devices include ambient light sensors and/or cameras to determine ambient lighting or other environmental information. Environmental information is used to adjust the brightness level of the display (e.g., the screen) for operation within the current context or location. For example, an ambient light sensor can provide an ambient score used to determine display modes such as reduced brightness, dark mode, true tone, and night shift. These adjustments take into account the ambient light in which the device operates and attempts to change the display mode as a function of the ambient score. Individually, these adjustments may be time-based according to local sunset or sunrise and may be switched to adjust the monitor or screen. These adjustments are made to the device's display to uniformly adjust the brightness level of the entire display. This may be done by increasing or decreasing the intensity of the backlighting of the display device's display, or by other means in the case of displays without backlighting. However, the viewing experience can be characterized by a wide variety of situations and/or conditions. Users can influence brightness settings by changing their position. Users may remain relatively stationary, but they may also watch different videos as part of a video content stream or scroll through various visual content (e.g., when using apps on a mobile phone to view short video clips in succession). A first video may have a low brightness level, while a subsequent video may have a higher brightness level. Videos and/or other content may, alternatively or additionally,
